I think the problem this movie is facing kind of the opposite problem Captain America did. Where as Captain America faced the issue of not coming across as a jigonistic, backslapping "America **** yeah!" film in the vein of Battleship and Transformers, Black Panther could potentially alienate Conservative American audiences if they're not careful.

A big part of Black Panther's storylines is that he's at odds with the West, and is 9 times out of 10, justified. That's not the sort of thing that will go over well in the red states, and whenever you make a movie that costs $100-200 M to make, you can't really afford to alienate half of the nation that will make up 1/3rd of your ticket sales.

I think they're trying to find that a-political take on BP equivalent to the relatively a-political take on Cap that popped up the MCU.
